How to select a single channel?

[tinker]

I'm using Audacity 1.2.5 on Intel Mac, OS 10.4.11. I opened a 2-channel AIFF file to learn to use Audacity (great - very powerful!) Now I want to delay one channel using time shift, but don't know how to select just one channel. I did do it once, by accident, and don't know how I did it. Help will be appreciated.

All you need to do is to use the Audacity function Split Stereo Track - this is available from the little downward-pointing black triangle in the track control box.

This will give you two separate tracks which you can manipulate individually.

If you need to to (and from what you describe, I suspect that this is what you want) you can subsequently remake them into a stereo track by using the Make Stereo Track - available from the black triangle in the track control box of the top track of the two.

Thanks, WC - just what I had in mind. Works perfectly!
